If the point(x, (sqrt3/3)) is on the unit circle, what is x?
------------------------------------------------------------

Then x = +/- sqrt%281%5E2+-+%28sqrt%283%29%2F3%29%5E2%29 = +/- sqrt%281+-+%283%2F9%29%29 = +/- sqrt%286%2F9%29%29 = +/- sqrt%286%29%2F3.

The tangent of 30 degrees is (sqrt(3))/3 so you're looking for y=1/2 x=(sqrt3)/2
